Allium perdulce, the Plains onion, is a plant species native to the central part of the United States and cultivated as an ornamental elsewhere.[1] It has been found in Texas, New Mexico, Oklahoma, Kansas, Nebraska, South Dakota, and one county in western Iowa (Woodbury County).[2][3]
Allium perdulceproduces 2-20 bulbs, each up to 3 cm (1.2 inches) in diameter. Flowers are urn-shaped, up to 10 mm (0.4 inches) across; tepals deep rose to purple (except in var. sperryi; see below); pollen yellow.[2][4][5][6]
Two varieties are recognized:[2][7]
Var. sperryi is a color variant known only from western Texas in the trans-Pecos region. It has white to pale pink flowers instead of the more widespread deep rose to purple.[2]
